New 8700c Can't Send Email

[shrimper dan]

Noob with a vexing problem. I just swtched from a 7100 on Cingular BIS to a new 8700 on an new corporate BES. Everything seems OK, getting emails, internet, sms, but.... when I try to send an email I get the error "Desktop email program unable to submit message". We have tried sending service books, deleting and restoring service books, a new Enterprise Activation. Nothing works. I set up the BIS link on this phone as the account is still active and that works fine. I had the problem prior to activating the BIS account on this handheld so I'm pretty sure that is not the problem.
Thanks for the help.

Sounds to me like you had the Redirector selected and your PC is turned off - or Outlook has closed.

Did you talk to you IT/BES guru?
